In the fourth film of the series, Sherlock Holmes assists the inventor of a revolutionary bomb sight, Dr Tobel, to smuggle his work out of Switzerland and into England. Once in England the bomb sight pieces and the Tobel go missing, leaving Holmes and Watson with code of dancing stick figures to break before Professor Moriarty so they can find the remaining pieces of the weapon.
